a pun on brainwashing...
Yep, glad you enjoyed it.
More seriously, once we let it fully register that Dumbledore is, like Barty Crouch Sr., willing to use Obliatus and Confundus against his own supporters--only for the Greater Good, of course--where do we think he drew the line?
That he used them on Minerva and Remus is supposition; that he supported their use on Marietta and Mundungus is canon. So he was guilty of using mental control spells; the question is how often and to whom.
And yes, he might--or Severus might, at his urging--have used them to blur memories that would lead his colleagues to question Severus's loyalty to Riddle.
My reason for supposing it more likely that Albus got his own hands dirty on this issue is that he was in a much better position to memory-charm the Order and staff than Severus was--especially in VoldWarI, when Severus wasn't even an official Order member.
